To al! 'w hom 'it may concern v Be .it known that l, 'Winterse v A. `VAN Benni, a citizen of the United States, residing at Horicon, in the county of Dodge and State ot llisconsin, have invented certain new and useful Improvements inSeeding` Figure el, are of the staggered spoke type.

Machines, of whichV the following is a specification, reference being` had `therein to the accompanying` drawing.

This invention relates to improvements in seeding` machines and particularly to that class or structures wherein. the devices Jfor -eeding' the seed from a hopper to fthe furrow openersare operatedby power furnished from the supporting,` wheels. v v

The principal object ot the invention is to improve the frame and axle construction and provide for more eiiiciently snp-` porting; the weight of the machine and the mass of seed carried in the hopper. The construction illustrated and` herein! after described is also an improvement from the standpoint oi' simplifying the inanutacturers roblem of furnishinn' a seeder in` a variety of sizes to meet the needs indifferent localities. for the outer sectionswhich carry the power transmitting` and speed va` riable means, are built as standardized units and can be used in the assembly of a inachine regardless of therwidth of its other parts.`

Another object oit the invention is tov improve devices ot1 this type in'sundry details hereinafter pointed out. o H

The preferred means bywhich 1 accomplish my objects are illustrated in the accompanyingl drawings and are hereinafter specilically described.

ln the drawings. .i

Figure 1 is a rear elevation of my im,- proved seeder, a number of the seed furrow openers being omitted at one side `to better show the axle construction.

Figure 2 is a verticalseetion on line 2-2 of Figure 1.

Figure 3 is a vertical section on line 3-3 of Figure 1. p

Figure 4 is a transverse vertical section on line 4*el of Figure 2, showing the speed"v varying and power transmitting means at one side of the machine.

Figure is a face view of the toothed speed variable disk, a portion o'j the disk be-` ing broken away to show the ratchet clutch arrangement, and

Figures Gand are enlarged details.

. Referring to thedrawings in which like` numerals indicate identical parts, 15 indicates the supporting wheels, which, as shown in The hub 16 oit each wheel is mounted upon a drive sleeve 17 and held in place by a threadedwasher 18. The sleeve 17 is caused i to turn with the wheel by interengaging' means such as a lug i'orined on the sleeve and iitting a recessin the whe at 19, Figure 4. i

j n i u l' u Lach drive sleeve 17 is mounted on a live el hub,` asindicated axle 2O and is seoured'thereto by bolt 21 so i the'wheel, sleeve and live axle all turn together. i

22 is a forwardly extending, substantially horizontally positioned, angle iron frame member, bent into the general forni of a U, with its intermediate portion `to the front,

therear end portions ot' the side sectionsbe` ing secured to boxings 23 journaled upon the sleeves 17@ Extending rearwardly from thetransv'erse or` `intermediate part of the U shaped frame member 22are frame members 211 that are secured at their rear ends to boxings 25 mounted on the ends of the centrallylocated dead axle or frame meinberQG,`

theboxings 25 also receiving and forming bearings for the inner ends oi the live axles Q0. A frame member 27 connects the center portion of' the transverse part of frame member 22 with a support E28 secured to the;

` the purpose being to gather the' wheels inwardly at the bottoni, the better to withstand the strains of the load and prevent the middle portion of the machine sagging. Many of the seeders `that goginto the fields are equipped with dished wheels, and this axle construction also provides in such cases for `the wheels being" so positioned that the spokes susiaining"V the weight stand perpendicular.

By the construction described the members 22, 24, 26 and 27, together with the boxings 23 and 25, constitute a light, rigid and strong frame which efficiently supports the live axles 2O in the desired inclined position, and cooperates with them to sustain the weight imposed upon them. At the same time, by this construction the live axles with the parts carried thereby may be standard-- ized to go with machines of a variety of widths.

The live axle sections are prevented from shifting endwise inthe following manner: i thrust washerv30 having convex bearing faces 31 is inserted in each boxing between the end of the live axle and the end of the dead axle, inwardpressure of they live axle beingtransmitted through this washer to the dead axle which is firmly held 'in its supports by the set bolts 29. The outward A23 contacts to resist outward thrust of said boxing, such'strain being carried back to the center dead axle or frame member 26, by reason of the' sleeve 17 being keyed to the live axle which in turn isheld from outward displacement by the collar 33 and cap 34.

Front and rear frame standards`40 and 41 respectively, secured at their lower ends to the rearward portion of the frame menibers 22--24 and 2,7, and the boxings 23, 25

and 27 the whole comprising a strong substantial machine frame.

A tongue 47 is pivoted at 48 to a bracket 49 supported by the center frame member 27 and the members 24. The transverse poi'- tionof the forwardly extending frame meniber 22 is connected with the tongue by a link 50 and a lever 51 pivoted at 52 upon the tongue and having the usual latcliing device 53 that coi-operates with a'notched sector 54. By adjusting lever 51 the frame can be set to level the seeding devices relative to the tongue, the angle of the tongue and its height from the ground at the front end `being governed largely by the size of the draft animals.

rlhe seed furrow openers illustrated in the other.

driving yplates in suitable pockets i drawings are of the disc type, although any form of furrow openers may be used as desired. ln this instance the disc 55 of each furrow opener unit is journaled upon an arm 55 of the seed boot 57. Connected with the arm 58and extending forwardly and upwardly isa drag bar 58which at its foi'- ward end is pivotally attached to the transverse section of the frame member 22 by a yoke 59. lThe elevation of or working position of the `furrow openers is controlled by a lever 60 which has a bearing 61 mounted on the dead axle 26. To the lower end of the lever at a linlr 83 pivoted, its other end being pivotally connected to an arm 64 clamped to a square roclr shaft 85, extending'across the front of the machine, and supported in bearings 65 attached to the braces 46. Clamped to the roclr shaft 65, at spaces throughout its length, are forwardly projecting Varms 67 to which are pivoted jointed Y'rods 68 that in turn are pivoted at their lower ends to the boot arms 56. Springs l69 are mounted on the rods '68, so the furrow openers can be put into the soil under yielding pressure and to permit one furrow opener to yield independently of an- Pivoted at 70 to the lower end of the levei' 50 .is 'a spring actuated plunger rod 71 slidably supported at its forward end in an eye 7 2'secured to the frame member 27. 73 is a heavy compression spring mounted on therod intermediate the eye' 72 and g. pin 71a through the rodT When the lever 60 inoved until the point 70 intersects the .tor 75,

ln the machine illustrated the seed feeding devices are operated by means of driving plates 7 6, oneof which is mounted upon each sleeve 17'and axle 20 so as to turn therewith and to be capable of movement longitudinally thereof. Near the periphery of these 77, are

mounted ratchet dogs 7 8 which are pressed outwardly'by springs 79. The dogs 78 cngage with ratchet teeth 8O formed on a drive disk 81, and the dogs are so positioned that as thewheel 15 and sleeve 17 turn forwardly one of the dogs engages a tooth 8O and carries the disk 81 forward. but if the wheel and sleeve turn rearward, as when themachinel is baclred, the dogs snap over the ratchet teeth 8() permitting the dislr to remain stationary, the hub of the plate 76 rolatine` in the bearing of the disk upon the plate indicated at '761. l

employ three sets o llO dll

`engagement with the" faces of the ratchet teeth, one slightly more than 'the other. The

purpose of this arrangement is to make the clutch sensitive or quick to respond to forward movement,"`it being desirable to apply power to the seed feeding devices promptly upon the Afirst forward movement ot the ina,- chine., and it likewise being undesirableto have the seed feeding,- devices operate upon backing the machine as when turning sometimes at the ends ott fields.` The driving plate and disk as an entirety may be sliii'ted inwardly on the sleeve 17, to disconnect the application of power to the seed feeding-.devices, by means of a ring S2 mounted on. the sleeve 17 between the hub of plate '76 and the benino; 23, the ring having),` a hand hold 83 (see l. and 2) by which it can be turned 'upwardly on the sleeve thus bringing a cam Se, formed on the ring, into gliding,- contact with av suitable surface on the boxing thereby shitting` the ring, plate and disk against the tension ci spring` 85, mounted on the axle between the hub ot plate 76, and` a` collar 86, fastened to the axle by set bolt 87. llhen the hand hold is turned in the opposite direction the spring presses the plate and disk in driving lcontact with its cooperating; part.

When the furrow openers are raised with the lever 60, arms secured to the rock shaft 65, near its ends, contact with the ends of bars 82a, the upper ends ot which are pivotally connected with the rock shaft by links 821 journaled on the rock shaft, and thel lower ends of which are pivotally attached to the 'forward side of the 82,'

and move the bars downwardly which turn the rings and shii't the drive plates and dii-iloI inwardly far enough to break the driw connection to the seed feeding devices theyT will be inactive. Tilhen the :tur-rou' oi'ie'ners are lowered 'the arms 65a rock away trom the bars Sil whereupon the weight oi. the hand holds 83 turns the rings l'and moves the bars upwardly, the drive plates end disks shifting,` into'driving position under the pressure of springs 85.

The outer face of each disk is provided with concentric rows of teeth 88,any one row oit which may mesh with the teeth 89 of a pinion 90. The purpose of the several rows of dist teeth is to furnish a multiplicity ol speeds for driving' the seed 'feeding wheels, their speed oit rotation varying as the pinion is shifted from one row of teeth to another. f

The pinion 90 is shiitably mounted upon and drives the vertically positionec. square shaft 99 the lower end oi which is supported by av button bushing 100 seated in the boxing sha sed member and. having` their inner end `ll-shapedi,'member disposed agprorimate,-`

` tions supported `by 4boxings.

23, `The shaiit 99 is a part of `the driving connections through which the seed delivering devices are actuated, but as such mechanism is not claimed in this application it will not be further describedherein.
